An all-weather roofing solution for both flat and pitched roofs. This innovative, one-component system is polyurethane-based and designed for easy application with a brush or roller.

Its expertly formulated liquid membrane creates a seamless, flexible, and durable waterproof barrier that suits new roof installations, refurbishments, or overlays on most common roofing substrates. No mixing, heating, or additional catalysts are required, allowing for straightforward, cold-applied use. What sets SikaRoof Liquid Membrane apart is its rapid curing capability, with the membrane becoming rain-resistant within a mere 10 minutes — even when pools of water form on its surface. Compatible with a wide range of materials, from concrete and metal to roofing felt and wood, SikaRoof Liquid Membrane offers unparalleled versatility. It bonds effectively to various substrates, including stone, fibre cement, roof tiles, and bituminous coatings, enhanced by full reinforcement when needed with Sikalastic Fleece-120. Whether you're working on a new construction project or refurbishing an existing roof, SikaRoof Liquid Membrane ensures a durable, crack-bridging protection that stands up to the elements, keeping your roof secure and reliable for years to come.
